Uniform and simultaneous orthogonal functionalization of a metal–organic framework material

Abstract

We exploit orthogonal chemical reactivity to generate uniformly multifunctionalized confined spaces in a simultaneous, one-pot reaction.

The post-synthesis modification (PSM) of MOFs for catalysis

“…For example, (B) a framework with orthogonally reactive tags yields a uniformly bifunctionalized MOF even in simultaneous reactions. 93…”

“…14A). 58,93,94 Taking advantage of the different reactivities of the tags, we have independently and quantitatively decorated MOFs with two different moieties, generating uniformly bifunctionalised MOF pores (Fig. 14B).…”

Efficient and strategical installations of quaternary ammonium groups in metal–organic frameworks for hydroxide conductivity

“…In the last two decades, various functional groups have been investigated for MOF functionalizations. [10][11][12][13][14] Pre-functionalization and post-synthetic covalent modification (PSM) have been studied to integrate organic functionalities into MOFs. Target functional groups can be installed in the organic ligand before MOF formation (i.e., pre-functionalization) or the desired organic group can be incorporated into the MOF after MOF formation using solidstate PSM.…”

Trisequential Postsynthetic Modification of a Tagged IRMOF-9 Framework

“…Since Cohen introduced the term “tandem modification” to represent a sequence of two PSM reactions, several tandem covalent procedures have been reported. − However, examples of sequential covalent PSM greater than two steps are limited to procedures on the ultrastable MOF MIL-101­(Cr) (a nitration–reduction–urea formation sequence and nitration–reduction–in situ azidation–CuAAC “click” sequences , ) and one example on a UiO-66-NH 2 skeleton (again featuring an in situ azidation–CuAAC sequence) . Such sequential PSM (sPSM) of MOF linkers is akin to organic synthesis inside a crystalline material.…”
